## 1. Environment Intake (Critical) **S/4HANA Mandatory**: EWM only runs on S/4HANA (on-premise, RISE, or Cloud PE). - **Embedded EWM**: Integrated in same S/4HANA instance (typical for manufacturing) - **Decentralized EWM**: Separate EWM system, multiple S/4HANA instances (complex networks) **Questions to ask user**: 1. Embedded or Decentralized EWM? 2. S/4HANA release year? (1909, 2020, 2021, 2022+?) 3. Warehouse network complexity? (single, multi-plant, 3PL outsourced?) 4. RF capability? (web-based, native app, mobile device?) 5. Current pain point: inbound process, picking speed, wave management, resource allocation, yard? --- ## 2. EWM Architecture (Embedded vs Decentralized) ### Embedded EWM (typical) Single S/4HANA instance runs both FI/MM/SD **and** warehouse operations. | Component | Table Prefix | Purpose | |-----------|--------|---------| | **Warehouse Master** | /SCWM/ | Warehouse structure, zones, resources | | **Inbound Order** | /SCWM/OBO | ASN → goods receipt → putaway | | **Outbound Order** | /SCWM/OBO | Sales delivery → picking → packing → ship | | **Warehouse Order** | /SCWM/OI... | Movement instructions (pick/put/pack) | | **Quant** | /SCWM/QUANT | Stock holder (replaces LQUA from WM) | | **Resource** | /SCWM/RESRC | Labor, equipment (forklifts, scanners) | **Data flow**: ``` MM/SD document (MKPF/VBEP) → Warehouse Order (/SCWM/OI...) ↓ RF/Web worker executes → Confirmation ↓ Post goods receipt/issue back to MM/SD (MKPF/VBEP updated) ``` ### D...
